Rate of Gain and Utilization of Feed as Affected by Different Levels of Sugarcane Molasses in Starting, Growing and Fattening Diets for Birds of a Laying and a Broiler Stock

Abstract

In several studies conducted during the starting and fattening periods of broiler stock, and the starting and growing periods of laying stock, levels as high as 20-percent sugarcane molasses were utilized satisfactorily in practical-type diets by the birds. Variations obtained in the different studies were discussed. Caked litter resulted with population densities of 0.19 m.2 (2 feet2) per bird when a 20-percent molasses diet was used, while semi-caked litter resulted with a level of 15-percent molasses. These results imply that with densities of 0.09 m.2 (1 foot2), equivalent to practical management conditions, a level of 10-percent molasses in diets appears borderline. Further corroboration studies seem to be indicated, to determine and recommend the maximum economical level of molasses in the diet which will not result in a compact litter. Feed cost data and their relation to the efficiency of utilization in these studies were evaluated. Inconsistent experimental data from previous experiments is discussed. A new technique for the homogeneous dispersion of molasses is described.
